Coastal Flood Advisory

Nantucket

Coastal Flood Advisory issued February 1 at 1:19PM EST until February 2 at 2:00PM EST by NWS Boston/Norton MA

Alert Description

* WHAT...Up to one foot of inundation above ground level in low- lying areas near shorelines and tidal waterways (5.5 to 5.7 feet Mean Lower Low Water). * WHERE...Nantucket MA County. * WHEN...Until 2 PM EST Monday. * IMPACTS...Low lying areas and roads near Nantucket Harbor, including Easy Street, may experience pockets of shallow flooding less than one foot deep. Sub-freezing temperatures and very cold road surfaces could allow storm surge to freeze, prolonging impacts and delaying drainage after high tide periods. * ADDITIONAL DETAILS...Two additional high tide cycles will result in pockets of minor coastal flooding. The first is very late tonight with the second around lunchtime Monday.

Safety Instructions
